To me, she just looks all around.... unclean.
But the reason that the general idea has survived is because when she first came out last year, she has this video where she is dildoing herself and she has dried, crusty menstrual blood on her thigh. And then there was another one where she had really, really dirty feet. And then another one where she had this.... sore on her leg that just looked really gutter.
She reminds me of these pretty mixed girls who grow up with the white trash side of their family.
